Description

Chronic pneumonia is said to be the most costly disease of swine in the world. Pneumonia causes considerable death loss in swine of all ages. It also causes poor performance, slow gains, and poor feed utilization in chronically infected animals. This condition is the number one problem of swine production today. Modern confinement rearing also contributes to the problem. Large numbers of hogs living in close proximity provide ideal conditions for the spread of infectious agents from one to another. Poorly managed swine facilities, with less than adequate ventilation "add fuel to the fire." At the present time there is no known specific treatment for many of these respiratory diseases. We must rely on prevention rather than on treatment. Diagnosis plays a very important role in these conditions because many of them resemble each other. Your veterinarian should be consulted, and if necessary he may enlist the aid of a diagnostic laboratory. There are many interactions between diseases. For example, swine that have atrophic rhinitis are more susceptible to pneumonia. The filtering capacity of the nasal passage is reduced due to damage to the turbinate bones. The presence of lung worms or migrating ascarid larvae can also predispose lungs to more severe infections. This fact sheet touches briefly on some of the most common respiratory problems encountered in swine production. This list is by no means complete.
